WATER-HEATER.

To all whom t mayconcern.' I I Be it known that I, FRED POOLE, a citizen of the United States, residing at Jewell, in

the county of Jewell and State of Kansas, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification.

This .invention relates to Water heaters,

and more particularly to that class of water heaters commonly termed instantaneous, and the structure illustrated in this application serves to set forth one of the several applications of my improvement.

The primary object of the present invention is to provide a form of instantaneous water heater which may be inserted in a-Water conduit at any desired point and in a manner which will least interfere Withthe passage of water through the conduit. I

Another object of the present invention is to provide a water heater of the above-mentioned class which affords a relatively large heatin area, thereby tending toward a more rapid eatin of the liquid coming in contact therewit Av still further object of the present invention is to afford suitable means for supporting the above-mentioned structure within awater conduit, and to associate Awith said supporting structure an improvedcircuit connecting lug.

With the above and other objects Vin view my invention resides preferably in the construction, combination, and arrangement of partsas hereinafter set vforth in the specification and illustrated in the accompanying drawings, in Which- Figure 1 is a side elevation of my invention showing its application to a Water conduit or the like, the conduit beinggbroken Fig. 2 is a longitudinal sectional view of my invention, the connecting plug being shown in elevation.-

Fig. 3 is a vertical sectional View through a portion of a water conduit and heater showingi my improved connecting plugin vertical section. A I

Similar reference characters indicatesimif lar parts throughout the various 'views of the drawings. I

Referring more particularly to the drawing in which the preferred'embodiment ofmy invention is illustrated, the numeralv 1 indicates a water or similar conduit of any I Specication of Letters Patent.

of the tubular members 6 and 7 beingin L threaded or other suitable engagement with the respective ends of the tubular members 4 and 5 as indicated at 8 to provide a substantially elliptically-shaped structure. The inner surfaces of the tubular members 4, 5, 6 and 7 are preferablyl lined with'some insulating' material such as asbestos as shown at 9, the said insulating .material being broken at 10 adjacent the points at which l VAthe sections 4, 5, 6, and 7 are joined. A resistance element of any suitable design is receivable within the tubular members 4, 5, 6, and 7 and is diagrammatically indicated, the numeral 11 designating this heating element.

Any suitable means may be employed for supporting the elliptical structure in spaced relation to the Walls of the conduit 12 but I have illustrated a `T-coupling which is provided with a nipple portion 12 which has its respective ends 13 and 14 connected to the tubular arm 5, the said tubular arm being divided at any desirable point for threaded engagement or the like with the said nipple 12.- The said portion 12 is provided with a right-angularly extending portion 15 which is secured to the conduit 1 as shown at 16 in Fig. 2 in any suitable manner,the.said right-angularly extending portionv 15 being tubular and serving yto act as an electric conduit for reception of electrical conductors of any type, connection being had with a source of electric energy in any suitable manner, a preferred manner being set forth hereinafter.v I

' In order to assemble the parts of the closed-loop pipe, the sectional casing 5 is placed to have its ends bearing against the nipple portion 12, while the casing 4 is positioned parallel to the sectional casing 5.

The arcuate tubular members 64 and/ are then placed to have their ends bearing upon Simulta neous rotation of the sections 4,I and 5 will the said casing 5 as indicated at 22.

cause their ends to be screwed into the nipple 12 and the arcuate tubular members 6 and 7, thus-assembling this closed-loop pipe.

It Will be seen from the above description that I have provided a heating element.

which is readily receivable Within a conduit, provides a large heating area and at the same time does not interefere in any substantial manner with communication through the conduit.

Any approved form of electrical connecting plug may be used for supplyingelectrical energy to 'the heating element, but I have illustrated a preferred form in'Fig. 3 of the drawing, wherein the conduit or the like is indicated by the numeral 1, as above, and is provided With a threaded opening 17. An externally threaded tubular bushing 18 is receivable Within the opening 17 and is locked therein by means of a spacing nut 19 and the gripping nut 20. rEhe inner end of a bushing 1S is securely locked in the casing' 5 in any of the many forms of heating elements which I provide, the said bushing 18 being in screw-threaded engagement with An insulating locking Washer 23 is threaded on the bushing 18 at the time of its insertion into the casing 5 for the purpose of preventing accidental movement thereof. A pro-.

tecting ring 21 surrounds the gripping nut 2O and is securely supported on the casing 1 by means of bolts 25, the said bolts 25 forming circuit terminals for electrical conductors 26, the terminals of'said conductors 26 being received on the bolts 25, and securely held in position thereon by means of lock nuts 27,.the circuit terminals proper comprising tvvo split arms 28 having rightangularportions 29v for engagement With the bolts 25. A plug'30 of any insulating material is provided having diverging communicating apertures 31 therein, said apertures 31 having the respective Wlres 32 o f an electric circuit carried therein, the termilnals of said electric conductors 32 being in electrical communication Withtubular members 33 open at their upper ends into which are receivablethe divided arms28. The di-l vided arms 28 are somewhat springy in nature and will retain the coupling plug 30 thereon When the same is forced into position by insertion of the arms 28 into the v"carried in the casing complemental tubular members 33, thereby completing a 'circuit to the heatingy element '5. 'As' illustrated ieariy in Fig. 3, itwin be madam the;

`,bolts 25 are provided With 'insulating' sleeves 25 While the conductors 26 are linsulated from the 'lower end of the vbushing 18 and from thegripping nut 20 as Well as the .l ring 24, by the insulating Washer 26f The electrical conductors 216l are retained in spaced relation to the Walls of the bushing 18 and each other by means of an insulating material 26 of any approved type, a cement being indicated. y

While I have shown and described the above form of my invention as possessing a peculiar form and construction, it is desired that it be understood that I may make such changes ih the details thereoflthat do not depart from the spirit and scope of the invention as claimed.

Having thus described my invention what -I claim and desire to secure by Letters Patent, is:

1. In a Water heater, the combination with a conduit, of a substantially elliptical tubular heating body disposed in the conduit, means arranged on the conduit for facilitating the mounting andremoval of the heating body therewithin, an electrical resistance element Within the tubular body,

an absestos covering for the element, a cou- ',pling member for the tubular body', binding connections having an insulated channel for supporting the tubular bodjy in the conduit,

electrical connections passing through the insulated channels, and joined with the resistance element, and spring terminals for the electrical connections..

2. In a Water heater, the combination of a. conduit, a tube consisting of a plurality of sections; interposed ,Within sald conduit, heating means Within said tube, a locking Washer positioned ini said tube, a spacing nut positioned between said tubing and said conduit-,a gripping nut positioned upon-the exterior of said conduit, an externally threaded bushing projecting through said conduit and one section of said tubing engaging said locking Washer, said spacing nut and said gripping nut, th'us causing the nut and bushing to space said tube and conduit apart and also forming a liquid tightl y FRED POOLE.
